Lsat week, Google rolled out Android 4.1.1 Jelly Bean to the Galaxy Nexus along with pushing the source code to AOSP. Android developers, including the CM team, has been working hard ever since then to merge the JB source code with CM9. Considering the framework changes in Jelly Bean, the CM team has to manually merge every patch which is a time consuming process.

Over the last few days, the CM team or some other developers have released ‘CM10′ preview builds, based on Android 4.1 Jelly Bean, for quite a few devices including the Galaxy Nexus. Today, joining the ranks of these devices are the U.S. variants of the Galaxy S III. Cyanogen himself has published the CM10 preview builds for the AT&T, Sprint and T-Mobile Galaxy S3.

Keep in mind that since this is a preview build it is far from stable, and does not even include all the features that CM ROMs are popular for including notification bar toggles, lock-screen widgets etc. If you do flash this preview CM10 build on your Galaxy S3, please don’t post that “xxx feature is not working”, since this is just a preview build.

Oh! and there is some good news for Verizon Galaxy S3 owners as well. The CM team has found a way to load and install a custom kernel on the big red’s variant of the SGS3 without unlocking the bootloader. They even managed to get CM9 to work, but due to some RIL related issues, have not released a preview build of CM10 for the handset.
